SA Monitor
This chapter teaches you how to manage your SAs by using the SA Monitor in SMT menu 27.2.
38.1 Introduction
A Security Association (SA) is the group of security settings related to a specific VPN tunnel. This menu
(shown next) displays active VPN connections.
When there is outbound traffic but no inbound traffic, the SA times out
automatically after two minutes. A tunnel with no outbound or inbound traffic is
"idle" and does not timeout until the SA lifetime period expires. See the Web
Configurator User’s Guide on keep alive to have the ZyWALL renegotiate an IPSec
SA when the SA lifetime expires, even if there is no traffic.
38.2 Using SA Monitor
1. Use the Refresh function to display active VPN connections.
2. Use the Disconnect function to cut off active connections.
Type 2 in Menu 27 - VPN/IPSec Setup, and then press [ENTER] to go to Menu 27.2 - SA Monitor.
